Mandatory winter tire requirements have commenced for most designated highways in British Columbia. The mandate, effective from October 1, 2026, remains in place until either March 31 or April 30, 2027, depending on the specific route. These regulations apply to most areas outside the Lower Mainland and southeastern Vancouver Island, and four-wheel or all-wheel drive vehicles are not exempt.

To comply with provincial law, tires must feature either the M+S marking or the three-peaked mountain and snowflake symbol on the sidewall. Additionally, tires must maintain a minimum tread depth of 3.5 mm. 

Enforcement is being conducted by the BC Highway Patrol, particularly in the Cariboo region. Non-compliance with tire regulations can result in a $121 fine and two penalty points, while driving with insufficient tread depth can incur a $109 fine. Authorities also maintain the power to turn vehicles around at checkpoints until they meet compliance standards.
